ROBERT J. GILMORE, OF PROVIDENCE, RHODE ISLAND.

RlNG-TRAVELER MACHINE.

SPECIFICATION forming part of Letters Patent No. 310,577, dated January13. 1885.

' Application filed September 21,1883. (X model.)

To all whom it may cancer/r.- Be it known that 1, ROBERT J. GILMORE, acitizen of the United States, residing at Providence, in the county ofProvidence and State of Rhode Island, have invented certain new anduseful Improvements in Ring-Traveler Machines; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters or; figures of reference markedthereon, which form a part of this specification.

This invention relates to machines for making ring-travelers orother'analog'ous articles; and it consists, first, of two pivoted andadjustahle shaping-formers,which receive simultaneous movement by meansof toothed levers operated by a single cam secured to the driving-shaft,in combination with suitable feeding and cutting-off mechanism.

The invention consists, secondly, of an ad- -justable and yieldingplunger, which rests against the traveler while it is being formed.

The invention consists, thirdly, of a hori zontal arbor providedwithmeans for intermittently moving the same endwise and means foradjusting the arbor radially, all as will be more fully hereinafter setforth.

The object of this invention is to provide a machine with means forproducing ring-travelers in abetter and more expeditious manner than hasbeen done heretofore. ,In the accompanying two sheets of drawings,Figure 1 represents a front elevation of the machine complete as in use.Fig. 2 is a rear view of the same. Fig. 3 is a detail view of thetoothed levers which connect with the shaping-formers. Fig. l is avertical section through the frame, plunger, and its plate.

Said figure also includes a front view of the same without the plate.Fig. 5 is a vertical longitudinal section showing the crank device. Fig.6 is an end view of the same. Fig. 65- is an enlarged sectional view,showing the horizontal arbor and its bearing. Figs. 7, 8, 9, and 10represent various forms the stock assumes during its formation into aring-traveler. These views also show certain details of the formingparts and yielding plunger. Fig; 11 is a ring traveler complete. Fig. 12

(Sheet 2,) is an enlarged vertical transverse section through the centerof the machine. Fig. 13 is a partial horizontal sectional view. Fig. 14is a partial view of the frame, showing one of the openings therein,within which one of the shaping-formers is located. Fig.

.15 is a front view of one of the shaping-formbushing which carries thesteel plate within I which the center arbor is mounted; and Fig. 22 is afront view of the plate itself.

The following is a detailed description of the invention:

A, referring again to the drawings, designates the vertical frame of themachine, which' is provided wit-h. bearings B for the main driving-shaftB. At each side of the frame, near its lower edge, are formed openingsA, Fig. 14., adapted to receive the holder for the movable formers, &c.

E, Figs. 1 and 2, represents a cam on the shaft B. .This cam impartsintermittent motion to the lever K, and said lever like motion to thefeed-rolls TT tlnrough the gear-train T T T.

It is a spiral spring, having one end fixed to the frame, and the otherend secured to the lever K. This spring holds said lever against the endof the set-screw 7c. The object of this screw is to adjust and limit thelength of stockto form the travelerfed along between the feed-rolls ateach revolution. At the'longest feed the friction-roll 76 may restagainst the face of the cam E; but as the feedis shortened so relativelyis the distance increased between the roll and the face of the cam, thisdistance being gaged by means of said screw k. The segmental toothed armof the lever K engages a gear-wheel, T, v (shown dotted,) which in turnis connected (by means of a pawl and ratchet, or otherwise, as common)with the larger gear-wheel T the latter meshing into the wheel T,secured to the shaft [1, carrying upper roll T is connected with thelower feed-roll by means of the set-screw T, which bears against a boxcarrying the upper rollshaft, as common. The stock a is intermittentlyfed along between the rolls T by means of said cam E, lever K, and thegear-train T T T, before described, D is a disk secured to saidshaft,having an eccentric groove formed upon its face, within which isloosely fitted the ring D, adapted to connect with the plunger orcross-head I by means of the pin d"'. The pin may be secured-to the ringand fitted into the plunger. The eccentricity of the groove and. ringcorresponds to the throw or stroke required. I I am enabled thereby todispense with the link or other intermediate connection usually requiredin transmitting power from the crank to the plunger, &e., thus peninitting the reduction of the height of the machine.

O is a cam secured to the shaft 1; for the purpose of giving suitablemotion to the lever F, the latter having a toothed segment, F. The leverF is fulcrumed at f to the frame. The lower portion, F", of said leverhas an elongated opening, f i A similarlever (without the arm F) ismounted upon the frame, and connected with its fellow just described bymeans of the cogs f, all as fully shown in Fig. 3.

s-is the steel former, around which the stock z is bent to form thetravelers 2', said former being secured within the arbor or spindleH, asfully shown in Fig. 12. A bushing, 1 having an enlarged center opening,1), is re tained in position and secured to the frame A in front ofthespi ndie H by means of the screw 0, passing up through the centerprojection or lug,V. A steel guide-plate, P, is fitted into the face ofthe bushing, having a center opening correspondingin size to the formers. In changing the formers, the screw 0 is loosened, after whichthebushin g, wit-l1 its plate, is removed, when, after inserting anotheror different-sized former, 8, within the spindle H, aplate, I having anopening of the same size as the former s, is inserted within thebushing, and the latter then replaced within the frame and secured inplace by said screw 0. Arbor H and formers are reciprocated by means ofthe cam-lug d, engaging the upper end of the lever d, (the latter beingpivoted at d to the frame,) whereby the main shaft in its revolutioncauses said arbor to move endwise intermittently, a spring, d, returningthe lever d, and thereby the arbor, to its normal position, all as fullyshown in Fig. 12. A bearing or support, A, secured to the rear .of themachine, carries the arbor. Its outer end is counterbored to receive thearm H, the latter being splined to receive a key or feather secured tothe arbor. By means of the arm H the former s is adapted to be slightlyadjusted radially without removing said former from the spindle. A bolt,71 serves to clamp the whole in position. I designates the main plunger,which is operated by the disk D, &c., before described. Said plunger isprovided upon its front surface with the two adj ustablysecured cutterst. (See right-hand portion of Fig. 4.). 7c designates a narrow plungermounted upon the front of the plunger I, and between the cutters 6*,Figs. 1, 4, and 12. Said plunger k is adaptedto rest upon the stockduring the cutting aud shaping process. It is further provided with anadjusting-screw, i", and spring i is the plate which covers the frontend of the plunger I.

\Vithin the frame-openings A are pivoted at O holders R, each of whichis provided with I a slotted arm,R",adapted to receive theclamping-screw a". Said holders are further provided with the elongatedopenings 1-", Fig. 18, and rear projections, r".

G is the block, which is adapted to sl ide freely within the holder R. Aprojection, r", fits within the openinga. A plate, 1 secured to saidprojection serves to retain the parts in position.

9 is a stud or pin of said plate, adapted to engage the slots f of thelever-arms F F, thereby causing the blocks to move in unison with saidlevers.

U represents the stud shapers or benders, pivoted ate to the slidingblock G. a shows an elongated opening therein, adapted to receive theclamping-screw a; and a is a screw which passes through the lug g of theblock G, for the purpose of adjusting the position of the shapersrelatively to the former s. The geared rolls T feed the stock along theguide at m and against the stop or gage Z, (see Fig. 1,) as common.

The machine operates as follows: Assuming that the formers, 850., havebeen properly adj ustedand the stock fed into position,now,by revolvingthe shaft in the arrow direction, the disk forces the plunger Idownwardly,the end IOC of the supplemental plunger is resting againstthe stock during the movement, Fig. 7. N ow, a further movement causesthe stock to be severed and bent downward by means of the cutters t,Fig. 9. During this latter travel, however, the plunger has remainedstationary, owing to the compression of the spring 2'. At this point,while the crank is passing its dead-center, the cam O, by means of thelever F aud connections,causes the steel benders and shapers U tosimultaneously move upward and inward, the points 8" thereof engagingthe projecting end of the stock, Fig. 9, and bending them into shape, asshown in Fig. 10. A. further movement of the shaft B causes the cam d toengage the lever cl, which in turn connects with the arbor H, Fig. 12,thereby forcing the latter rearward and bringing the face of the formers flush with the steel plate P,thus causing the finished traveler z tofall into a receptacle or chute beneath, completing the revolution.

In Fig. 8 the plunger 70 is not shown, thus former s after the cutters ihave performed their functions. It is obvious that travelers IIO thusproduced must necessarily be imperfect; but by means of the yieldingplunger 7; the work is rendered perfect and salable.

The arbor H and bushing l? are adapted to receive formers 8 havingvarious sizes and shapes. The steel shapers U are also provided withmeans for adjustment, and further adapted to produce travelers havingthe ends bent square instead of hooking, as shown, by means of thepivoted and radially-slotted holder R.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination of the driving-shaft, disk D,plungers I is, pivoted lever d, arbor H, and former s, the parts beingconnected and operated substantially as described, and for the purposesset forth.
